UN: Officials are realizing sex abuse cases may be more widespread.

"Rocked by widespread abuse of women and girls, including gang rape, in the Democratic Republic of the Congo, the United Nations also has found sexual exploitation cases in at least four other missions -- in Burundi, Liberia, Ivory Coast -- as well as more recently in Haiti, they added. "We think this will look worse before it begins to look better," Jane Holl Lute, assistant secretary general for peacekeeping operations, told reporters. "We expect that more information will come from every mission on allegations. We are prepared for that."
